What We Do (1 of 2)

  • Groundwater Determinations:

– SWR 13: Set and cement sufficient surface casing to protect all usable quality water strata (BUQW) – New Drills, Injection, Re-entry, Recompletion, P&A, H-15, O&G Water Supply (W-1 if deeper than BUQW)

  • Geologic Isolation (H-1, W-14)

– No injection is allowed in Underground Source of Drinking Water (USDW)* – Depth of confining clay or shale below BUQW/USDW

4

slide-5
SLIDE 5

Railroad Commission of Texas | June 27, 2016 (Change Date In First Master Slide)

What We Do (2 of 2)

  • Cathodic Protection and Microseismic wells

– CP (SWR 99) and MS (SWR 100) – Required if depth is >30 feet – W-1 required if CP/MS well exceeds protection depth – Submit well schematic of CP/MS well with W-1 – GW-1 for CP/MS wells cannot be used for other purposes

  • Special Projects

– Capitan Reef (BEG) – BRACS/ASR – Texas Water Development Board (TWDB)

Water Classification

  • Superior Quality Water (SQW) < 1,000 ppm

– Good tasting drinking water

  • The Base of Usable Quality Water (BUQW) < 3,000 ppm

– Protection depth as define by SWR 13

  • Underground Source of Drinking Water (USDW) <

10,000 ppm

– No injection allowed in the USDW* * Aquifer Exemption or EPA concurrence

Water Board Letters

  • Why do we call them Water Board Letters?
  • Texas Board of Water Engineers established 1913
  • 1950 Order required operators to obtain a TBWE letter

Railroad Commission of Texas | June 27, 2016 (Change Date In First Master Slide)

How do we Protect?

  • Provide Depths for Surface Casing, Cementing, and Plugging
  • Locate Geologic Isolation For Injection Wells (H-1, W-14)

– Depth of confining clay or shale below USDW is required 250’ Below BUQW with 100’ contiguous confinement

10

slide-11
SLIDE 11

Railroad Commission of Texas | June 27, 2016 (Change Date In First Master Slide)

Casing and Cement (1 of 2)

  • SWR 13 requires that surface casing protect

groundwater as stated in Groundwater Advisory Unit (GAU) letter (Form GW-2)

– Surface Casing

  • Protects usable-quality water from

drilling/completion process

  • Extra protection against leaks during production

– Cement

  • Prevents annular migration of fluids
  • Prevents corrosion of casing
  • Isolates formation

11

slide-12
SLIDE 12

Railroad Commission of Texas | June 27, 2016 (Change Date In First Master Slide)

Casing and Cement (2 of 2)

  • Three layers of protection: surface casing, production

casing and tubing

Application (Form GW-1)

  • Requests for Groundwater Determinations can

be made one of two ways

– Use the RRC On-Line System – Download a PDF form on the GAU Website

  • Email the completed GW-1 form to gau@rrc.texas.gov
  • Send the completed GW-1 form through regular mail

SLIDE 15

Railroad Commission of Texas | June 27, 2016 (Change Date In First Master Slide)

Reason for Filing

  • Important for H-1 and W-14 because determination will

include the USDW necessary for UIC permit application

15

Areal Extent

  • Areal Extent

– May request Radius, Section, Abstract, Lease… – Provide additional information in “Remarks” (ex: specify well API numbers to be included) – Extent depends on hydrogeology & topography
